BC-DW Flat-Blade Backward Inclined Centrifugal Fan, DWDI Application 离心风机通常用于需处理大流量、低中压空气的常规暖通与工业应用中。暖通风机用于商用建筑的排风、送风与回风系统。工业风机应用于包括喷漆室排风、过滤系统、空气污染控制和各类工艺系统等。 The BC-DW Centrifugal Fan is designed to handle large volumes of relatively clean air as required in heating, ventilating, and air conditioning systems as well as many industrial air supply and exhaust applications. Wheels are constructed of steel using flat, single thickness blades that are solid welded to the rim and backplate. The inlet-side rim is designed as a proper companion for the inlet cone. All wheels are statically and dynamically balanced to grade BV3 per AMCA 204 and provide smooth operation prior to being assembled in the fan, followed by final balance of the entire rotating assembly. All BC-DW fan housings are continuously welded and reinforced with rigid bracing to increase structural integrity.
